Moreover, there are indeed copper smelters, steel smelters, sodium smelters, etc. in the old industrial area, and there are more than one.

For example, in the previous case, the glass particles found on the victim's body were ejected from the chimney of the copper smelter.

At this time, Chen Xu suddenly said:

“I also made a discovery!

冂, it seems to refer to copper!"

He uploaded a picture directly in the group.

Is it really copper?

How was this conclusion determined?

All the group members were very curious and immediately checked the pictures uploaded by Shen Xu.

This picture was drawn based on Shen Ting's Hummer trajectory map.

There are many traces in the picture, but there is only one!

That's a straight line!

From Sanyapo, the pond where the criminals threw the Hummer, there is a straight line leading directly to the old industrial area!

The group members were a little confused.

The same goes for Shen Ting.

What does it mean to directly connect the pond and the old industrial area?

There is no direct connection between them? !

Kiko: "?_??"

Guan Hongyu: "What does this picture mean? I don't understand it."

Tang Ren: "You kid, are you kidding us?"

Qin Feng: “???”

Shen Xu left a direct message: “That’s right.

The group leader just uploaded the pictures and confirmed that the suspected base was an old industrial area, and then I suddenly realized it.

In the Hummer, the direction in which the three dead men were kneeling seemed to be the old industrial area!

I judged the direction in which the three people were kneeling when the Hummer was in the water based on the pictures taken by the frogman before the Hummer was salvaged and the kneeling postures of the three deceased after the Hummer was salvaged.

Using the location of the Hummer sinking pond as the point, draw a line in the direction of kneeling.

What is drawn is the straight line on the graph!"
